COIN-FREED MECHANISM.

Application filed. October 24, 1919. Serial No. 332,974.

To all 107mm it may concern:

Be it known that THOMAS GLovnn, a subject of the King of Great Britain, residing at Edmonton, London, England, has invented certain new and usefullmprovements in Coin-Freed Mechanism, of which the following is a specification.

This invention relates to that class of coin receiver employed in coin freed mechanism comprising two cups having slots for receiving the coin, one cup being fixed to a shaft of the operating handle and the other cup loosely positioned thereon and connected to the operating mechanism and especially to a mechanism of the class just indicated such as is employed in coin freed gas meters and wherein a train of wheels connecting the loose cup with this operating mechanism is utilized but my invention is also applicable to other revolving types of coin receiver.

Now the object of this invention is to pro vide means whereby the coin slot is opened only when the two cups are in proper position to receive the coin and closed during the whole of the operative movement of such cups so as to prevent any fraudulent tampering with the cup or cups to operate the mechanism.

The invention will be described with reference to the accompanying drawings, wherein:

Figure l is a side elevation, partly in section, showing the coin receiver in position to receive a coin, the coin slot in the casing being open.

Figure 2 is a front elevation of Figure 1 and showing a casing to which the coin receivers are connected.

Figure 3 is a similar view to Figure 1 but showing the coin receivers at the discharge position and the coin slot in the casing closed.

Figure 4 is a front elevation of the apparatus in the position shown in Figure 3.

For the purpose of my invention I provide the shaft A. with a segment of a disc, or strip B and connectsame to one of the cups C such disc segment or strip B being of larger diameter than the cups C, D.

One end E of the segment or strip B is positioned near the coin slot F in the cup C and the other end G approximately dia metrically opposite to said slot.

Between the coin opening H of the casing I and the coin slot of the carrier a shaft J is pivoted, said shaft J carrying a strip K of such a. size and shape as to cover the coin slot Hin the casing I and such shaftJ also carries a flag or wiper L which is acted upon by the edge of the disc segment or strip 13. The flag or wiper L may be a continuation of the strip K. i I

i/Vhen the carrier is in position to receive a coin, as shown in Figure 1, the strip K and wiper L hang down and clear of the coin opening H in the casing, leaving said opening free, but when the coin carrier C, D is turned the end of the disc segment or strip B acts upon the wiper L and rocks the shaft J to cause the strip K to close the coin opening H in the casing I and the wiper L rides along the edge of the disc segment or strip B as will be understood from Figure 3 for the whole movement of the carrier in both directions, i. e. until the carrier 'C, D has completed its movement and been returned. Just as the carrier C, D is brought back into position to receive a fresh coin the strip K and wiper L drop by gravity to normal position and the coin opening in the casing is opened.

The inside of the casing next the coin opening may be provided with a ledge M or tube to act as a guide for the coin and a stop N is provided for engagement with the strip B when the coin carrier has completed its movement in either direction.

What I do claim as my invention and desire to secure by Letters Patent is 1. In coin controlled mechanism, an operating shaft, a pair of rotatable cups having coin receiving slots, one of said cups being fixed to said shaft and the other being loosely mounted on said shaft and connected to an operating mechanism, an enclosing casing having a coin slot, a strip hinged-at one edge in said casing adjacent said coin slot and adapted to swing into and out of position to cover said coin slot, and means secured to one of said coin receiving cups and adapted to rotate with said cup and when said cup is rotated, to engage said strip and swing it into position to cover said coin slot, and to maintain said strip in position over said slot until the cup has rotated a predetermined distance.

2. In coin freed mechanism, an operating shaft, a pair of cups having coin receiving coin slot, a strip hinged in said casing parallel to said slot and adapted to swing into and out of position to cover said coin slot, a Wiper carried by said strip, and a segment carried by one of said cups adapted, when said cup is rotated, to engage said Wiper and swing said strip into position to cover said coin slot.

3. In coin controlled mechanism, an operating shaft, a pair of rotatable cups having coin receiving slots, one of said cups being fixed to said shaft and the other being loosely mounted on said shaft and connected to an operating mechanism, an enclosing casing having a coin slot, a strip hinged at one edge in said casing adjacent said coin slot, means in the form of the segment of a disk secured to one of the cups and adapted to rotate therewith, the outer periphery of said segment being adapted to contact With and maintain the strip in position to close the coin slot during a. portion of the rotation of said cup.

In testimony whereof I have hereunto set my hand in presence of tWo subscribing Witnesses.
